Refactor DataMaster and implement Passport sign in for Facebook and Google.
Create two folders and move the appropriate files into it:
export CLIENT_SECRET= ``` You should of, course, put your **CLIENT_ID** and your **CLIENT_SECRET** in place of the prompts shown above. Something like this: export CLIENT_ID=1234 When you are done, load the file: **source set-env**. Then check your work: ```bash echo $CLIENT_ID echo $CLIENT_SECRET ``` You should see your Client ID and your Client Secret. This is safe because the file is on the server and will not be seen by visitors to your site. You might, however, want to lock this file down with draconian permissions (chmod 400) to make sure that no one can edit it and only you can read it. For now, I would like you to place the **set-env** file in your repository. Be sure, however, that you are using a private repository! If you decide, in the future, to make this a public repository, then be sure to change your Client Secret on the Facebook web site.
